I have a question about gale's palette saving. When i uploaded my palette into Advance Map, it gave me the "multiple colors" error, but when i went to correct it, i discovered to my horror that the colors were completely wrong and sometimes seemed to be entirely random. I think its a problem with Gale, because when i tried to import the palette to Photoshop to see if i could fix it from there, it gave me another error. When i load the palette in Gale, however, it works perfectly. Have you encountered this error before, or do you know how to fix it?

Thank you for bringing this to my attention, I'm looking into it as I type this message.
There are two things that come to my mind that could be the problem:
1.) Gale doesn't index images and that could be the problem. In some cases it will grab exact colors, and other cases it wont. When you save a palette in gale with a un-indexed image it gets a lot of other unneeded colors. Or it could be a palette file that only Gale can read.
2.) .PAL files are a bit messed. I've had troubles with .PAL files before. I'm going to look deeper into this for you and edit my post/PM you with the results.

EDIT: Ok, I've narrowed it down and it is because Gale doesn't index images. If your tile set has over 16 colors, it will load with a palette like this, which is way too many colors:

Nice tutorial! Other tutorials are good too but this explains a lot.
Can I just paste the tile without 16 colors to the 16 colors instead of coloring it?

I mentioned this in one of my "Did you know" tips; you can paste a tile that you want recolored into another image that's indexed. It will automatically change it's colors. BUT there's two things:
-You have to be really careful because sometimes it will give the tile you just pasted bad colors.
-If it's over 16 colors, it will usually not come out the way you want since it has so many colors. You can try it though.

You should try this if the image your pasting the tile to has similar tiles, like a cliff into a rock tileset.
